Objective Cを使用してBluebambooデバイスで画像を印刷するには？

Question

私は客観的なC開発で新しく、私が外部アクセサリーを使用しているプロジェクトで作業しています。そのデバイスはBluebamboo P25Mプリンターとクレジットカードスワッパーです。

このプリンタを使用して画像を印刷する必要があります。 BluebambooはSDKを提供しましたが、このSDKではchar型のビットマップイメージの配列を使用しています。今、私はどのような画像を印刷することができるように私のイメージのような配列を作成することができます。ここで

Answer 1

そのプリンタのイメージデータの形式は指定しません。それはRGBですか？ CMYK？ CMY？

私は一般的な質問は、どのように画像の生のバイトで取得すると思います。これを行うには複数の方法があります。まず、イメージのTIFFバージョンを取得できます.TIFFをデータ形式で変換できますか？

NSImage *myImage = ...; 
NSData *bytes = [myImage TIFFRepresentation]; 

NSDataを取得したら、write：ルーチンのバッファ（rawバイト）とバッファの長さを取得できます。

は、より一般的に、あなたは次のようにビットマップ表現を作成することができます

CIImage *myImage = ...; 
NSBitmapImageRep *bitmapRep = [[NSBitmapImageRep alloc] initWithCIImage:myImage]; 
NSData *jpegData [bitmapRep representationUsingType:NSJPEGFileType properties:nil]; 

[jpegData WRITETOFILEを：@ "/ユーザ/ユーザ名/デスクトップ/ MyImage.jpegを" アトミック：YES];

これは、JPEG形式の生のバイトを提供します。
